Abstract
Erratic power supply from the utility grid has grave effect of the development of several countries. In a bid to
overcome this challenge, many residential buildings have become electrically self-sustaining by the integration of
various backup power supply source. Yet the act of transition from one source to another has remained a manual
task that tends to discourage users from going through the rigour. Internal combustion engine AC generators and
batteries have been found to be the most common backup options. An automatic transition system that gives user
the flexibility of monitoring and controlling resources remotely from a mobile phone application is thus presented
in this paper. The microcontroller-based system monitors the status of the energy resources and protects the
building against undervoltage or overvoltage conditions. Based on the state of charge of the battery and the fuel
level in the generator, the system activates the appropriate alternative backup source in the event of an outage form
the grid supply. This system affords users a new level of comfort and reliability of power supply, as in the automatic
mode, the users are guaranteed power supply with minimal downtime, except when all resources are unavailable.
